Abstract

Microstructural and mechanical investigations have been performed on a new class of silicon-disilicide eutectic composites comprising a Si matrix and reinforcing (Cr,V)Si(2) disilicide phase. These composites are east from the liquid and undergo anomalous eutectic solidification, during which loosely coupled growth of the consitutent phases results in a wide range of eutectic morphologies depending on the volume fraction (V(f)) of the minor phase. As the chromium content is varied from 0 to
